In East-Central Europe, Marxist humanism embodied one of the most promising theoretical developments of the 1960s. While respecting the unquestionable value of this intellectual current, this article highlights the contradiction between the emancipatory proclamations of humanist intellectuals and their reluctance to recognize certain prevalent forms of oppression. After comparing the humanist approach toward gender-structured themes in the former Czechoslovakia with the contrasting techno-optimist approach, the latter group is shown to have been more sensitive toward women’s issues. Th e article concludes that there was an intrinsic problem in Marxist humanist theory that contributed to this historical shortcoming in its emancipatory eff orts.
The sequence diversity in the mitochondrial cytochrome-c oxidase I (COI) gene was evaluated as a tool for resolving differences among species of European adelgids collected from several localities across the Czech Republic. Members of 7 genera and 16 species were examined, and as outgroups, two species of Phylloxeridae were used. Sequence divergences within species were on average less than 0.15%, whereas divergences between species ranged from 0.0 to 4.12% for congeneric and to 13.24% for intergeneric comparisons. It is concluded that DNA barcoding of Adelgidae is a powerful tool for identifying genera, but at the species level it works only in those cases where there are no species complexes. Nevertheless, it can be used as a complement to traditional, morphological taxonomy.
